Abstract:
In recent years, cognitive radios and cognitive wireless networks have been introduced as a new paradigm for enabling much higher spectrum utilization, providing more reliable and personal radio services, reducing harmful interference, and facilitating the interoperability or convergence of different wireless communication networks. Cognitive radios are goal-oriented, autonomously learn from experience and adapt to changing operating conditions. Cognitive radios have the potential to drive the next generation of radio devices and wireless communication system design and to enable a variety of

Abstract:
The main objective of this dissertation is to develop the second generation of Distributed Digital Radio (DDR) technology. A DDR II modem provides an integrated voice/data service platform, higher data rates and better throughput performance as compared to a DDR I modem. In order to improve the physical layer performance of DDR modems an analytical framework is first developed to model the Bit Error Rate (BER) performance of Orthogonal Frequency Division Multiplexing over Frequency Modulation (OFDM/FM) systems. The use of OFDM provides a spectrally efficient method of transmitting data over LM

Abstract:
The tremendous ongoing growth of wireless digital communications has raised spectrum shortage and security issues. In particular, the need for new spectrum is the main obstacle in continuing this growth. Recent studies on radio spectrum usage have shown that pre-allocation of spectrum bands to specific wireless communication applications leads to poor utilization of those allocated bands. Therefore, research into new techniques for efficient spectrum utilization is being aggressively pursued by academia, industry, and government. Such research efforts have given birth to two concepts: Cognitiv

Radio technology is rapidly evolving and as processing capabilities and algorithms become more complex, the need for alternative compilation and user interface abstraction increases. Field Programmable Gate Array (FPGA) technology introduces unique reconfigurable hardware architectures that can aid in software defined radio (SDR) design. FPGAs have greater processing capability than traditional general purpose processors (GPP) found in desktop workstations. This work builds on an ongoing project, GReasy, that augments a Linux based open source SDR development platform, GNU Radio, with FPGA pro

Abstract:
Syfte: Syftet med denna uppsats är att undersöka hur publikmedverkan förändrats i public service-radion i och med digitaliseringen. Publikmedverkan ska undersökas ur flera aspekter men med ett särskilt fokus på nya medieformer. Teori: Då en enskild relevant teori saknas för området publikmedverkan inom public service-radion har tidigare forskning från flera närliggande områden sammanställts i en för uppsatsens syfte unik analysmodell. Denna modell konceptualiserar infrastrukturen för publikmedverkan i public service-radion. Den beskriver hur den tekniska utvecklingen och public service-uppdrag

Abstract:
Cognitive radios have been proposed as a new technology to counteract the spectrum scarcity issue and increase the spectral efficiency. In cognitive radios, the sparse assigned frequency bands are opened to secondary users, provided that interference induced on the primary licensees is negligible. Cognitive radios are established in two steps: the radios firstly sense the available frequency bands by detecting the presence of primary users and secondly communicate using the bands that have been identified as not in use by the primary users.<p><p>In this thesis we investigate how to improve the

Abstract:
This thesis is a creative and critical exploration of "radio poetry" -poems commissioned and produced for radio transmission, which utilise a verse-script, sound effects, music and other sonic materials as part of their poetic make-up. It argues that radio poetry has been overlooked in both literary criticism and radio studies, because of the ephemerality and ubiquity of its medium, and on account of the absence of a fully developed critical framework for its analysis. The thesis is intended to redress such a lack, and to outline the potential of radio poetry as a mode of sono-poetic expressio

Abstract:
Approved for public release; distribution is unlimited<br>The shift from wired to fully wireless communication is causing an increasing demand on the frequency spectrum. The cognitive radio was introduced to solve spectrum scarcity by allowing spectrum sharing between licensed and unlicensed users. This approach presents a challenge to source localization because of the cognitive radio’s capability to shift its spatial, frequency and temporal parameters. The extended semi-range-based (ESRB) and cooperative-received-signal-strength-based (CRSSB) localization schemes are proposed to overcome the

Abstract:
<p>Radon is a hazardous substance that cannot be perceived by our senses. It has long been known that exposure to high radon levels for a long period of time will ultimately cause lung cancer. The Swedish Radiation Safety Authority estimates that 500 people die annually due to this. Although most of them are smokers, even non-smokers suffer from lung cancer caused by radon. The statutory value for radon in homes today is 200 Bq/m³. Several years of research points to the fact that 63% of all those who develop lung cancer have been exposed to radon levels between 100-200 Bq/m³. This is why the
